Will Donald Trump boycott the next debate?

Donald Trump is one debate down — but how many more does he have to go?

There are two more debates scheduled, but based on his history, not everyone's convinced he'll go through with them.

Back in January, Trump boycotted a Republican primary debate and instead held a rally for veterans. It didn't seem to hurt him, as he knocked down his competitors to win the nomination for president.

In August, he again threatened to sit out the first debate against his opponent Hillary Clinton.

"I have to see the conditions," Trump told Time. He complained that the debate would air during NFL's Monday Night Football, and he wanted to see who would be the moderator before deciding whether to participate. "I would say that certain moderators would be unacceptable, absolutely."

Ultimately, NBCNightly News anchor Lester Holt moderated Monday night's debate, as the two squared off at Hofstra University. Trump had a "rocky" performance and blamed a faulty microphone.

"They gave me a defective mic!" he told reporters after the debate, according to a video posted by CBS News executive producer Mosheh Oinounou. "... I wonder, was that on purpose?"

Now one of Trump's top surrogates, former New York City Mayor Rudy Giuliani, wants Trump to boycott the next debate because of Holt's performance as moderator.

"If I were Donald Trump I wouldn't participate in another debate unless I was promised that the journalist would act like a journalist and not an incorrect, ignorant fact checker," Giuliani said.

Fact-checking became an issue in the debate after NBC's Matt Lauer was criticized for his performance as moderator of the "Commander in Chief Forum" earlier this month.

On Monday morning, Clinton's campaign expressed concern that Trump would not be fact-checked during the debate.

"We are concerned Trump may lie and throw misinformation out there and that Hillary will have to spend all her time trying to correct the record, rather than [talk] about the things she wants to talk about," Clinton's campaign manager Robby Mook told CBS This Morning.

"All that we're asking is that the record be checked, and so if Donald Trump lies, which he has repeatedly done in the past, that that be simply checked," he said.

Trump said he didn't want any fact-checking — or even a moderator.

"Let Hillary and I sit there and just debate because I think the system is being rigged so it's gonna be a very unfair debate," he told CNBC earlier this month, according to Politico.

The morning after the debate, Trump blasted Holt's performance as moderator, saying he asked much easier questions of Clinton.

"He didn't ask her about the emails ... he didn't ask her about her scandals, he didn't ask her about the Benghazi deal," Trump told Fox News' Fox & Friends on Tuesday morning. "... He didn't ask her about a lot of things that she should have been asked about. ... Why? I don't know."
